Abstract: Scholastic test grading apparatus uses a circular answer sheet having a circular series of angularly-spaced, numbered rows of radially-spaced answer spaces on which the student marks his answers to correspondingly numbered questions by blacking-in selected ones of the answer spaces as with soft pencil lead. The sheet also carries punch locating indicia opposite each number. The answer sheet is graded by pressing it, in a selected orientation, against a printed circuit board which has formed thereon a pattern of electrical gaps corresponding to the correct-answer positions on the answer sheet. The blacked-in pencil lead blacking material in such positions bridges the electrical gaps to close electrical circuits to a circle of lamps, which light up to show both how many and which answers are correct. A question label disk placed in the circle of lamps identifies the questions or groups of questions indicated by the several lamps.
